Based on 500 SUS oil at 701.
0
F ambient. Heavier oil will produce fewer but larger drops.
When approaching maximum outputs, some oils will stream rather than form drops in sight glass. 2.
For operating pressures over 50% of the rated maximum , consult the factory.3.
Allowable viscosity range independent of temperature: 80-5000 SUS.4.
Maximum allowable inlet pressure: Pressurized pump, 100 PSI; Pressurized pump with sight glass, 10 PSI.5.
NOTE: Any static positive pressure applied to the pump inlet has the potential to cause leakage flow through a pump at rest or adjusted for zero stroke unless offset by a check valve
of comparable pressure rating located at the pump outlet. The "discharge check valve" pictured has no spring and is rated at zero PSI. The "outlet check valve" pictured in
phantom in view at bottom of next page is rated at 35 PSI.

*When configured from the factory to fit into Model 55, Mega, Lincoln or Premier Box Lubricators, the vacuum pump has a 0.875 in shortened suction tube.
**Model 88B, C and E pumps can be field modified to fit Mega, Lincoln and Premier Box Lubricators. Remove the strainer, break off the suction tube at the V-groove, and
replace the strainer.
†Graco will provide pump replacement only, customer to supply tubing and fittings for rear, front and shutoff pumps.
